The current geochronological data do not permit close resolution of either the timing or the duration of Deccan volcanism; the age of the bulk of the material is placed in the range ∼70-60 Ma. Further resolution of this hypothesis awaits acquisition of high-quality 40Ar-39Ar plateau ages on key sections of the Deccan Traps. This content is PDF only. Please click on the PDF icon to access.
